Fixed code P0420 on a 1996 Tacoma 2.7, installed this cat, passed California smog test

Self install to fix DTC P0420. Prior to this repair, I took my 1996 Tacoma DLX 4x4 5 Speed 2.7L 4 Cylinder 3RZ-FE to my trusted mechanic to have the fuel trim and O2 sensor checked. Then I bought this part, Toyota OEM gaskets and new grade 10.9 fasteners and it happened. I have a smartphone based OBDII device handy, I used it to clear the code after tightening the last bolt, then drove 50 miles on the freeway to a smog-only test station and passed .

Pros
  • Catalysts and parts
Cons
  • All OK

Because it is one of the best Toyota engines for 4 cylinders.

Bought this part number to install a '98 Tacoma Pre-Runner with a 209,000 mile 2.7L 4 cylinder 3RZ-FE. Why put a new cat on a car with such high mileage? Because it's one of the best Toyota engines ever built for 4-cylinder engines, it still burns clean and runs smooth! The cat "fits" where the old one was, but it's not quite the "straight fit" as advertised. Be sure to get the correct spacers for both ends of the new cat, they are not supplied and the new ones from the factory seem to work…

Pros
  • Catalytic Converters
Cons
  • Lightly dented
